CAS-1371: Fixed a bug where requiring to create sessions at the JSP layer gums up the next login attempt from that browser session within the servlet session duration.
CAS-1332: Making the logger instance available to extensions.
CAS-1334: Adjusted ArgumentExtractor's javadoc to match interface behavior.
CAS-1371: Fixed a bug where requiring to create sessions at the JSP layer gums up the next login attempt from that browser session within the servlet session duration.  This can be reproduced via:

1) log in to an application via CAS.
2) Log out from application, terminating application-local session and redirecting to cas/logout .  This terminates previous and issues new servlet session with corresponding JSESSIONID cookie.
3) without closing browser, try to log in to the application again via CAS.  This deposits you to the CAS login form, of course.
4) correctly complete and submit the CAS login form, but be rejected! CAS redirects back to and displays login form again, issuing a new JSESSIONID.
5) correctly complete and submit the CAS login form.
Merge branch 'CAS-1371' of github.com:Unicon/cas into CAS-1371

CAS-1382: D&D functionality of mgmt app

Removed unused import "Cas20ProtocolValidationSpecification"
Fix IV handling in clustered environments (EncryptedMapDecorator.java)

Patch for EncryptedMapDecorator.java (cas-server-extension-clearpass). Returns IV (16 bytes) prepended to ciphertext on encrypt(); mandatory for proper decryption. Useful in clustered environments where IVs saved to thread-safe ConcurrentHashMaps are being stored locally in memory, thus rendering other systems in the cluster unable to decrypt a ciphertext without the original IV being made accessible. This solves the problem by including the IV as part of encrypt()'s return value. Added IV_ROUNDS and SALT_ROUNDS for demonstration purposes.

See https://gist.github.com/rdev5/7570750 for details.
